Abstract

A profiled element (1) includes a tubular blank (2) which is formed into the desired shape by hydroforming. In conjunction with hydroforming, at least one slot essentially in the longitudinal direction of the blank is made in wall portions (4, 6) on the blank, and a reinforcing element (3) is fixed in each slot. In a suitable embodiment, each reinforcing element is fixed in two opposite slots and extends through a cavity in the blank. The invention relates to on the one hand a profiled element and on the other hand a method of producing the same.
